Check if array value contains specific value in html

Question

I have a array in angularjs like below:

var test=["abc/1/1","def/2/2","efg/3/3"];

I want to check if an array contains value having "abc" in it in html

I checked:

test.indexOf("abc")!=-1

but its returning false

I have populated array in JS and i want to check if array contains value containing abc in html.

button form="myAttributeAdd" type="submit" data-ng-disabled="" class="btn btn-success btn-xs"> Save

This is button element in my html. here data-ng-disabled will be true or false depending on array data.If array data value contains abc it will be enabled else disabled

You can use RegExp to search abc inside it.

//getting html value
var valueToFind = document.getElementById('htmlCode').innerText;

function findValue(findString) {
  //getting arrays to be find
  var test = ["abc/1/1", "def/2/2", "efg/3/3"];
  //creating the regex
  var reg = new RegExp(findString);
  
  //a.match will show the output
  console.log(findString,test.some(a => a.match(reg)))

  console.log(findString,test.filter(a => a.match(reg)))

}

//invoking the function
findValue('abc');
findValue(valueToFind);

<div id="htmlCode">efg</div>
